Influence of expressed emotion and perceived criticism on cognitive-behavioral therapy for social phobia

This study examined significant others' expressed emotion (EE) and a closely related construct, perceived criticism, as predictors of cognitive-behavioral therapy outcome in a sample of 40 patients with social phobia (social anxiety disorder). Patients enrolled in group therapy for social phobia completed pre- and post-treatment questionnaire measures of perceived criticism and anxious and depressive symptoms. Designated significant others were assessed for the components of high EE (criticism, hostility and emotional overinvolvement) using the Camberwell Family Interview. It was hypothesized that these high-EE components and patients' perceived criticism would be associated with poorer treatment outcome, and results ran counter to these expectations. Controlling for initial social phobia severity, lower levels of perceived criticism predicted treatment dropout. There was also a nonsignificant trend for participants with a significant other rated as high in emotional overinvolvement to show less change on a composite symptom measure. Findings from this study suggest that close relationships impact the outcome of cognitive-behavioral interventions for social phobia.     

Inhibitory control and empathy-related personality traits: sex-linked associations

We here report two studies exploring associations between inhibitory control (measured with the Sustained Attention to Response Task, SART) on the one hand, and self-reports of trait cooperativeness and empathy on the other. A coherent picture was obtained in women whose inhibitory control proficiency predicted higher scores on the Temperament and Character Inventory Cooperativeness and a higher Empathy Quotient. Individual differences in working memory did not predict self-reported empathy. In men, the association between SART performance and empathy was less clear: Good performance on the inhibitory task predicted lower scores on Cooperativeness and was unrelated to the Empathy Quotient. In both studies, women outperformed men on the SART. The results in women may reflect how individual differences in elemental neuro-cognitive operations such as inhibitory control influence more complex functions such as social cognition.     

Kontroverse zu Beschwerdenvalidierungsverfahren bei der Begutachtung psychischer St?rungen

The value of symptom validity tests in a forensic context is currently the subject of a controversial debate in Germany. The discussion primarily focuses on neuropsychological symptom validity tests, however, tests specific for mental disorders are neglected. Unfortunately, no assessment tools for symptom validation of mental disorders of German origin are available and adaptations of available English state of the art instruments have not yet been tested. Further research of assessment development and qualitative analysis of the decision-making process in medicolegal evaluation is needed in German speaking countries.     

Beliefs About Psychological Services (BAPS): development and psychometric properties

A scale to measure attitudes towards seeking psychological help was developed (Beliefs About Psychological Services [BAPS]) and evaluated. This scale was based on items gathered from students, colleagues, and the authors when asked about common positive and negative attitudes toward psychologists and their services. Items were also based on the Fischer and Turner (1970 Fischer, EH and Turner, JLeB. 1970. Orientations to seeking professional help: Development and research utility of an attitude scale. Journal of Consulting and Clinical Psychology, 35: 79–90. [Crossref], [PubMed], [Web of Science ®] [Google Scholar]) Attitudes Toward Seeking Professional Psychological Services (ATSPPH) measure. Three studies are reported describing the construction and evaluation of the psychometric properties of the BAPS. The BAPS is an 18-item measure consisting of three subscales: Intent, Stigma Tolerance, and Expertness. Support was found for the reliability and validity of the measure.     

A model of working memory capacity in the radial-arm maze task

The radial arm maze is one of the most commonly used tests for assessing working memory in laboratory animals. However, to date, there exists no quantitative method of estimating working memory capacity from performance on this task. Here, we present a mathematical model of performance on the radial arm maze from which we can derive estimates of capacity. We derive explicit results for the two most commonly used measures of performance as functions of number of arms in the maze and memory capacity, assuming a uniform random search. We simulate random non-uniform search strategies. Comparing our model to previous experiments, we show that our model predicts a working memory capacity in the range of 3-9 at the level of performance observed in these experiments. This estimate is within the typical estimate of human working memory capacity. Performance of rats on large mazes (e.g. 48 arms) has been used as evidence that the working memory capacity of rats may be significantly larger than that of humans. We report that memory capacity in the range 3-9 is sufficient to explain the performance of rats in very large radial mazes. Furthermore, when we simulate non-uniform random search strategies observed in the experiments, the resulting estimates do not differ significantly from those assuming a uniform random search. We conclude that a list-based model of working memory with modest capacity is more powerful than previously expected.     

Observation and physical practice: coding of simple motor sequences

An experiment was conducted to determine the coordinate system used in the development of movement codes during observation and utilized on later physical practice performance of a simple spatial-temporal movement sequence. The task was to reproduce a 1.3-s spatial-temporal pattern of elbow flexions and extensions. An intermanual transfer paradigm with a retention test and two transfer tests was used: a mirror transfer test where the same pattern of muscle activation and limb joint angles was required and a nonmirror transfer test where the visual-spatial pattern of the sequence was reinstated on the transfer test. The results indicated a strong advantage for participants in the physical practice condition when transferred to the mirror condition in which the motor coordinates (e.g., pattern of muscle activation and joint angles) were reinstated relative to transfer performance when the visual-spatial coordinates were reinstated (visual and spatial location of the target waveform). The observation group, however, demonstrated an advantage when the visual-spatial coordinates were reinstated. These results demonstrate that codes based in motor coordinates can be developed relatively quickly for simple rapid movement sequences when participants are provided physical practice, but observational practice limits the system to the development of codes based in visual-spatial coordinates. Performances of control participants, who were not permitted to practise or observe the task, were quite poor on all tests.     

The precuneus and the insula in self-attributional processes

Attributions are constantly assigned in everyday life. A well-known phenomenon is the self-serving bias: that is, people’s tendency to attribute positive events to internal causes (themselves) and negative events to external causes (other persons/circumstances). Here, we investigated the neural correlates of the cognitive processes implicated in self-serving attributions using social situations that differed in their emotional saliences. We administered an attributional bias task during fMRI scanning in a large sample of healthy subjects (n = 71). Eighty sentences describing positive or negative social situations were presented, and subjects decided via buttonpress whether the situation had been caused by themselves or by the other person involved. Comparing positive with negative sentences revealed activations of the bilateral posterior cingulate cortex (PCC). Self-attribution correlated with activation of the posterior portion of the precuneus. However, self-attributed positive versus negative sentences showed activation of the anterior portion of the precuneus, and self-attributed negative versus positive sentences demonstrated activation of the bilateral insular cortex. All significant activations were reported with a statistical threshold of p ≤ .001, uncorrected. In addition, a comparison of our fMRI task with data from the Internal, Personal and Situational Attributions Questionnaire, Revised German Version, demonstrated convergent validity. Our findings suggest that the precuneus and the PCC are involved in the evaluation of social events with particular regional specificities: The PCC is activated during emotional evaluation, the posterior precuneus during attributional evaluation, and the anterior precuneus during self-serving processes. Furthermore, we assume that insula activation is a correlate of awareness of personal agency in negative situations.     

Vigilant Self‐regulation and Costly Punishment in Public Goods Situations

Applying regulatory focus theory to the context of social dilemma situations, the present research demonstrates that individual differences in vigilant, prevention‐focused self‐regulation predict the tendency to invest private resources to punish uncooperative interaction partners (costly punishment), a behaviour that typically has strong positive effects on the collective level of cooperation. Analyses further support the distinctiveness of the vigilance system proposed in regulatory focus theory (prevention focus) in comparison with general defensive inhibitory tendencies (measured with Carver and White's Behavioral Inhibition System scale). Results document that individual differences in prevention‐focused self‐regulation but not differences in general defensive inhibitory tendencies are positively related to costly punishment. In sum, the findings indicate that vigilant, prevention‐focused self‐regulation plays a crucial role in the context of sanctions that enforce cooperation.

Correlates of Dispositional and State Flow in Tennis Competition

The purpose of this study was to investigate the relationship between psychological correlates and flow in tennis competition. Using a cross-sectional design, the sample of 261 junior tennis athletes showed moderate-to-strong correlations between flow (dispositional and state) and confidence (r _disp = .59; r _state = .35), imagery use (r _disp = .58; r _state = .32), and action control (r _disp = .41; r _state = .40), whereas absorption was orthogonal to flow. Commonality analysis revealed that imagery and confidence accounted for 34.2% of the variance in dispositional flow. The results are discussed for the development of intervention studies in order to enhance flow in competition.
